Introduction

Linear equations are a fundamental concept in mathematics, and solving them is a crucial skill for students and professionals alike. In this article, we will focus on solving a simple linear equation, $10.2 = 0.6y$, to demonstrate the step-by-step process involved.

What are Linear Equations?

A linear equation is an equation in which the highest power of the variable(s) is 1. It can be written in the form $ax + b = c$, where $a$, $b$, and $c$ are constants, and $x$ is the variable. Linear equations can be solved using various methods, including algebraic manipulation, graphing, and substitution.

The Equation $10.2 = 0.6y$

The given equation is $10.2 = 0.6y$. To solve for $y$, we need to isolate the variable $y$ on one side of the equation. This can be done by performing algebraic operations on both sides of the equation.

Step 1: Divide Both Sides by 0.6

To isolate $y$, we need to get rid of the coefficient 0.6 that is multiplied by $y$. We can do this by dividing both sides of the equation by 0.6.

# Given equation: 10.2 = 0.6y
# Divide both sides by 0.6
y = 10.2 / 0.6

Step 2: Simplify the Expression

After dividing both sides by 0.6, we get $y = 17$. This is the solution to the equation.

Solution

The solution to the equation $10.2 = 0.6y$ is $y = 17$.
